Abstract
The invention discloses method for implementing mobile instance communication (MIC) by using handset in Socket direct connection mode in order to overcome shortcomings existed in MIC by using handset in HTTP short connection mode recently. Characters are that using Socket mode, the handset builds connection with server; when data communication is carried out, sending party sends information to server, the server pushes information to the receiving party to realize instance communication, and receive and transmit in realtime; when no data are communicated, each server and client end sends data packet in interval in order to keep interconnection, and update user's state in time.
Description
Technical field
The present invention relates to the mobile immediate communication field, particularly a kind of mobile phone is realized the method for mobile immediate communication in the direct-connected mode of Socket, this method is that mobile phone uses Socket direct-connected, cooperation by client and server realizes instant messaging, just a solution of various ways instant messages such as the direct receiving and transmitting voice of server, literal, picture, video, annex.
The direct-connected mode of Socket: be applied in the mobile immediate communication field, be meant that mainly client and server sets up point-to-point connection, information adopts the mode that pushes, and is delivered to client by server via mobile data network.Socket can translate into Chinese: the mode of using standard Unix filec descriptor (filedescriptor) and other program communication.Usually socket is also referred to as " socket ", is used to describe IP address and port, is the handle of a communication chain.Application program is sent to network by " socket " usually and is asked or reply network requests.
Mobile phone described in the literary composition is that system supports the TCP/IP procotol, and the mobile phone of SOCKET network api interface is provided.
Background technology
General mobile immediate communication is to set up the short connected mode of HTTP between the client and server now.This mode is mainly, and client is initiated request to server when the needs data communication, connects and sets up; Client is obtained information from service end; Generally be that mode with poll (regularly inquiry) receives information from server, server can not initiatively be sent out message to client, wait client that can only be passive brings in the cancellation breath, and instant messaging has in fact become pseudo-real-time communication, promptly sends message and receive message to have certain delay.The short connected mode of this HTTP can disconnect when not communicating by letter, client request server once more when needing.
Make and carry out mobile immediate communication in this way, a lot of drawbacks are arranged, be mainly reflected in:
1. use the short connection of HTTP, server can not initiatively be sent out message to client, and wait client that can only be passive brings in the cancellation breath, and instant messaging has in fact become pseudo-real-time communication, promptly sends message and receive message to have certain delay.
And, because the characteristic of mobile data network, when client with being connected a period of time when not having data communication between the server, its connection is in " dormancy " state automatically, just can't guarantee that at this time state of user upgrades automatically, can not satisfy in the communication needs of knowing User Status constantly, as the needs of online, off-line, various states such as leave, have much to do.
3. this connected mode, message are to send to server, and client receives with the form of packet from the server by receiving again.Even just the recipient connects with server, to wait for that also client receives packet fully from service end, just can listen to and watch, can not reach the immediate effect that reception is at any time play at any time.
4. this connected mode needs client periodically to connect with setting up data between the server, and just polling server is obtained the information of oneself.Client periodic polling server is in the normal data transmit status to keep client with the connection between the service end, is exactly " heart time " during this.This " heart time " length is difficult to grasp." heart time " is long, send information to the time that other clients receive information from a client and will prolong the delay that causes instant communication message to receive." heart time " is too short, and then cell-phone customer terminal sends data message and can increase mobile network's flow with the frequent connection between the service end, brings huge pressure to network, causes communication speed slow.And cell-phone customer terminal sets up once connection by mobile data network with server or every initiation is once asked, and all can expend the mobile phone electric weight, and when the mobile phone frequent requests, power consumption is fast.
5. this connected mode, the customer end adopted poll obtains information, and the HTTP visit capacity is directly proportional with client login amount, and the network bandwidth and the handling property of server required all than higher.And information will be stored in service end, brings in for the reception client and obtains, and is also very high to the storage capacity requirement of server.
Summary of the invention
The present invention is directed to the short connected mode of existing mobile phone HTTP and carry out the defective or the deficiency that exist in the mobile immediate communication, provide a kind of mobile phone to realize the method for mobile immediate communication in the direct-connected mode of Socket.
Technical scheme of the present invention is as follows:
A kind of mobile phone is realized the method for mobile immediate communication in the direct-connected mode of Socket, it is characterized in that: mobile phone adopts Socket mode and server to connect, when the user carries out data communication, transmit leg send information to server, the server push carry information is given the recipient, to realize instant messaging, real-time tranception information; When not having data communication, the server and client side sends at interval separately keeping interconnective packet, and the User Status that upgrades in time.
Described mobile phone adopts Socket mode and server to connect and refers to, and behind the mobile phone logging on client, client and server is set up Socket and connected.
Described transmit leg send information to server and refers to, the user uses client to send literal, picture, voice, video or accessory information to server, and the client judgement of transmission lays oneself open to normal transmit status, and information is passed to server by the order from information header to the information tail.
Described server push carry information refers to the recipient, and server from receiving information header, is pushed to receiving terminal to information after judging that receiving client is in normal accepting state in order, transmits up to the information tail and finishes; This propelling movement process, server is stored information not, and information directly sends receiving terminal from transmitting terminal via server in the mode of stream.
Also comprise step: oneself be not in normal transmit status if the client that sends is judged, then client is got up information stores, waits for that normal condition sends.
Also comprise step: if server judges that receiving client is not in normal accepting state, server can get up information stores, waits for that receiving terminal is in the information of carrying out again under the normal condition and sends.
Described is a small data packets to keep interconnective packet.
Described small data packets can be a simple byte.
Described simple byte is " space ".
Described interval is sent as periodic interval and sends.
The described User Status that upgrades in time refers to, and server receives that the error message of returning is to connect the signal that disconnects, and server judges that in view of the above client loses connection, the replacement User Status.
Technique effect of the present invention is as follows:
The invention provides the direct-connected mode of a kind of mobile phone Socket and be applied to technology in the mobile immediate communication, the point-to-point pushed information of server client, the information that guaranteed is instant to send instant the reception; Needing to have avoided client constantly to inquire about the time delays of obtaining information.And the server and client side sends out packet mutually, has kept connection, has eliminated User Status and has upgraded untimely situation, has solved and has rebuild the electric energy that connects the pressure that brings to network traffics and saved user mobile phone.This method is that a kind of real-time is good, and the efficient height is saved the mobile phone electric energy, saves network traffics, simultaneously to hanging down the solution of mobile immediate communication cheaply of hardware requirement.
The main effect of this scheme is embodied in:
1. real-time is good, and speed is fast, the communication efficiency height.Owing to adopt the direct-connected mode of Socket, give the recipient with regard to the efficient transfer that adopts the mode that pushes to carry out point-to-point information as long as server is received information.Connect than HTTP, need the client periodic polling, fetch the information of oneself, fast a lot.As making a phone call and sending e-mails; It is real-time making a phone call, and sending e-mails then needs terminal request to receive from server, and real-time is good inadequately.
2. instant reception is watched immediately/is listened.Because server one receives message, just is directly passed to the recipient, information passes to the recipient according to the mode of stream from transmit leg, and server is stored information not, and this has just realized that information receives immediately, the instant parsing.Especially fast for information rates such as voice, videos, with receiving with broadcast.Do not need to wait for that all receiving the back plays.
3. User Status can upgrade in time.Because Socket is kept after connecting foundation always, the server and client side keeps connecting, the renewal client state that service end can be instant; The short FAQs that connect of HTTP such as " false online " or connection " dormancy " state have been avoided.
4. do not need to rebulid connection when the user thinks data communication.Client is connected in order to keep with service end, the activation of giving out a contract for a project mutually.When needs were communicated by letter, the user did not need to rebulid connection and obtains information, thereby had guaranteed that the information that the user needs can send and receive immediately.
5. save the mobile data network flow, save the mobile phone electric weight.Inquiry has or not information because client does not need regularly to server, can reduce taking mobile data network greatly; More can save the mobile phone electric weight to a great extent.
6. server requirement is not had the short connected mode height of traditional HTTP, save development cost.Do not need regular inquiry, the server access amount is more much lower than traditional approach, requires all not have so high to the network bandwidth of server and handling property.Under normal condition, directly transmission information of server is given client, does not need storage, does not consume to account for too many server resource, and the short connected mode of HTTP requires so not high to server stores relatively.
Description of drawings
Fig. 1 realizes the workflow diagram of mobile immediate communication in the direct-connected mode of Socket for a kind of mobile phone of the present invention.
Embodiment
Further the present invention is described in detail below in conjunction with accompanying drawing.
The present invention adopts the direct-connected mode of Socket to carry out mobile communication, is to cooperate to come realization information to send the solution of reception immediately by client and service end.Behind the mobile phone logging on client, client and server connects.When the user need communicate by letter, use client to send information such as literal, picture, voice, video or annex to server, server judges whether be in normal condition, if be in normal condition, server is pushed to the reception client to information if receiving client.This propelling movement process, server is stored information not, is directly passed to receiving terminal in the mode of information flow.If the user does not need to communicate for a long time, do not disconnect in order to guarantee to connect, client and service end send small data packets according to certain time interval to the other side separately, connect to activate, and upgrade User Status timely.Like this can be when needs be communicated by letter, in time pushed information can be kept connection again when not needing to communicate by letter, in case need communication, can send information immediately.The direct-connected employing server push of Socket mode is transmitted information, has more real-time, high efficiency, high-speed; The server and client side sends out small data packets again mutually and activates connection always.Finally can save flow and saves energy, low hardware requirement is saved development cost.
At first, core of the present invention being described, is that mobile phone uses the direct-connected mode of Socket to carry out mobile immediate communication, and by the point-to-point pushed information of server and client side, realization information is sent to immediately, and periodically sends out packet with client and service end and keep being connected.Finally can improve information transmit-receive efficient and transmission speed, and save the mobile data network flow and save the user mobile phone electric energy, promote the user experience of mobile immediate communication business.
Further specify mechanism and concrete steps as shown in Figure 1 that this maintenance connects, wherein:
1) user selects to login cell-phone customer terminal in the direct-connected mode of Socket.
2) whether the user needs data communication, if change 3 over to); If not, change 6 over to).
3) user's edit file is ready for sending.
4) client judges whether to lay oneself open to normal transmit status:
4.1) be in normal transmit status, then information is passed to server by the order from information header to the information tail;
4.2) be not in normal transmit status, then client is got up information stores, waits for that normal condition sends.
5) server is received information, judges whether receive client is in accepting state;
5.1) be in normal accepting state, then push information to receiving terminal.From receiving information header, in order information is pushed to receiving terminal, transmit up to the information tail and finish.
5.2) not being in normal accepting state, server stores information then is when waiting for the receiving terminal normal condition.
6) client and service end are sent out packet mutually according to the rational time interval separately, keep connection.
7) whether service end receives the error message of returning.
7.1) return error message, lose connection, the server update User Status.
7.2) do not return error message, connect maintenance
8) it is direct-connected that client and service end keep Socket.
When sending and receiving client and all be in normal condition, use Socket to connect, information adopts the mode of point-to-point propelling movement between client and server.The instantaneity that guarantee information is listened to while transmitting/seen.The direct-connected mode of Socket, server is pushed to client to information, makes client when using mobile immediate communication, the not free delay.Client and service end are sent out packet mutually with certain rational time interval separately, keep Socket and connect, and user profile is sent in real time sent to, and User Status upgrades in time.When the user sent information, client was issued server to information header to the order of information tail, and server receives client and can receive limit parsing, instant watching/listen by edge joint from receiving that information header begins just information to be pushed to the reception client.Both just transmission or reception client were not in normal condition, can avoid user profile to lose by client or service end storage yet.The packet that client and service end are sent out mutually is in order to activate connection, can be a very little character, as " space " etc., does not take a large amount of mobile data network flows.Server receives that the error message of returning is to connect the signal that disconnects, and server judges that in view of the above client loses connection, the replacement User Status.
In the described step 1), the cell-phone customer terminal login is to set up Socket with server to be connected.Described mobile phone needs only system and supports the TCP/IP procotol, and provides SOCKET network api interface to get final product.
Described step 2) in, communication then can transfer immediate news if desired; If do not need communication, then keep connection according to later step.
In the described step 3), user's edit messages mainly comprises by cell-phone customer terminal and edits literal, recorded speech, recorded video, takes pictures, adds various ways such as annex.
Described step 4.1) in, if client is in normal transmit status, information then can directly be delivered to receiving terminal via server push.
Described step 4.2) in, if the user is not in normal transmit status, for the user needs, client can be preserved information and be sent after being in normal condition.
Described step 5.1) in, if receiving terminal is in normal accepting state, server will just be pushed to receiving terminal from receiving information header, send up to transmitting terminal and finish.Server is not preserved information in the process, but transmits information in the mode of data flow from the transmitting terminal to the receiving terminal.
Described step 5.2) in, if receiving terminal is not in normal accepting state, for fear of drop-out, this moment, server can stored information, waited for when receiving terminal is in normal condition, and the information of carrying out again sends.
In the described step 6), client and server is all sent out packet at a certain time interval mutually, does not disconnect in order to keep Socket to connect in fact, for guaranteeing the user when needed, can communicate by letter immediately, does not need to rebulid connection; User profile can be sent to immediately, does not need to obtain separately; And connect and keep energy real-time update User Status.
In the described step 7), server is received when mistake is returned sending out packet, assert that client loses connection.
This method is applied in the mobile phone instant messaging in the direct-connected mode of Socket, and the point-to-point pushed information of server client has guaranteed that instant the transmission immediately of information receives; Needing to have avoided client constantly to inquire about the time delays of obtaining information.And the server and client side sends out packet mutually, has kept connection, has eliminated User Status and has upgraded untimely situation, has solved and has rebuild the electric energy that connects the pressure that brings to network traffics and saved user mobile phone.This method is that a kind of real-time is good, and the efficient height is saved the mobile phone electric energy, saves network traffics, simultaneously to hanging down the solution of mobile immediate communication cheaply of hardware requirement.
The present invention is directed to the short connected mode of existing mobile phone HTTP and carry out the defective or the deficiency that exist in the mobile immediate communication, provide a kind of mobile phone to carry out the solution of instant messaging in the direct-connected mode of Socket.This programme mobile phone adopts Socket mode and server to connect, and when the user needed data communication, transmit leg sent information to server, and the server push carry information is given the recipient, to guarantee instant messaging, real-time tranception information; When not having data communication, each sends out packet mutually with certain suitable time interval the server and client side, and to keep connection, User Status upgrades in time.
Technical conceive of the present invention: adopt the direct-connected mode of Socket to carry out mobile communication, cooperate to come realization information to send the solution of reception immediately by client and service end.Behind the mobile phone logging on client, client and server is set up Socket and is connected.When the user need communicate by letter, use client to send information such as literal, picture, voice, video or annex to server, server judges whether be in normal condition, if be in normal condition, server is pushed directly to the reception client to information if receiving client.This propelling movement process, server is stored information not, and information directly sends receiving terminal from transmitting terminal via server in the mode of stream.If client is not being carried out data communication, do not disconnect in order to guarantee to connect, client and service end send small data packets according to certain time interval to the other side separately, connect to activate, and upgrade User Status timely.Like this can be when needs be communicated by letter, in time pushed information can be kept connection again when not needing to communicate by letter, in case need communication, can send information immediately.The direct-connected mode of Socket is transmitted information, has more real-time, high efficiency, high-speed; The server and client side sends out packet again mutually and keeps connecting always.Finally can save flow and saves energy, low hardware requirement is saved development cost.
The present invention is mainly mobile phone and sets up the direct-connected solution of carrying out instant messaging of Socket.This programme mobile phone adopts Socket mode and server to connect, and when the user needed data communication, transmitting terminal sent information to server, and the server push carry information is given the recipient, to guarantee instant messaging, real-time tranception information; When not having data communication, each sends out packet mutually with certain suitable time interval the server and client side, and to keep connection, User Status upgrades in time.Its feature may further comprise the steps: step 1, and the user uses the cell-phone customer terminal login, selects the direct-connected mode of Socket; Step 2, after the login, the user needs communication, then edit file.Step 3, the client judgement of transmission lays oneself open to normal transmit status, and information is passed to server by the order from information header to the information tail; Step 4, server then from receiving information header, is pushed to receiving terminal to information in order as judging that receiving client is in normal accepting state, transmits up to the information tail and finishes.Step 5, when not having data communication, service end and client according to the rational time interval that configures, are sent out small data packets separately mutually, keep connecting, and User Status upgrades in time; Step 6 is not returned error message if server is received, then connects always to keep.Step 7, client keeps being connected with service end always, in case data communication is arranged, skips to step 3.
" select the direct-connected mode of Socket " in the described step 1, can set the direct-connected mode option of Socket, select the back login, set up the Socket connection exactly in client.
Described step 2 " user needs communication, edit file then " mainly comprises by cell-phone customer terminal and edits literal, recorded speech, recorded video, takes pictures, adds various ways such as annex.
